Currently I have a third party control that generates a Metafile. I can save the .wmf file to disk with out issue. The problem is how do I render the Metafile as a Tiff file. Currently I have the following code to get my metafile and save it.
Dim mf As Metafile = page.GetImage(TXTextControl.Page.PageContent.All)
Dim enhMetafileHandle As IntPtr = mf.GetHenhmetafile()
Dim h As IntPtr
Dim bufferSize As UInteger = GetEnhMetaFileBits(enhMetafileHandle, 0, h)
Dim buffer(CInt(bufferSize)) As Byte
[Code] .....
I've tried all sort of Image and Graphic calls and just can't save the meta file as a .tiff. I even tried to create a new bitmap and draw the metafile onto it. I always end up with a GDI exception being thrown.

I have a little piece of code which saves a certain Bitmap to a JPG image. The Bitmap is "composed like this" ( Ppiechart is a picturebox):[code]So After it is declared I start to do some drawing on this bitmap. And then I want to save it like this:[code]So this saves the image. But the problem is that the background of the image turns black when I open the file on my PC.The background of the Bitmap in the program itself is white. So does anybody have an idea what may cause this? Do I have to declare a color for the "mybitmap"?

I have the following code found on internet:
Const WM_CAP_START = &H400S
Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:
'---save the video data into the Image global variable---
Public Sub CaptureImage()
Dim data As IDataObject
Dim bmap As Image
Dim ms As New IO.MemoryStream()
'---copy the image to the clipboard---
[Code] .....
The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.

I am working on developing a program that needs to keep the data of radiobuttons, textboxes, comboboxes, etc. and it needs to be able to save several files(one for each different user). I found a quick solution from a forum, but it will only save the data from a textbox, or a tabpage. The solution that i have came up with, is to use the data, put it into a textbox, to save,then when it opens the file, it will use the data and put it back into the controls. (EX.)
If
TextBox30.Text =
"Full"
Then
[code]....
This does work but it does reduce some flexibility, and takes alot more programming than what is needed. I am looking for a simple way to save the data, and retrieve it.

Here is a short program to demonstrate my question. I just want to extraxct a rectangle bitmap from a big bitmap.Code as follows:
Private
Sub Button3_Click(ByVal sender
As System.Object,[code]....
Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:
"MissingMemeberException was unhandled.
No default member was found for type 'bitmap"
I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.
